| 摘要 |
The invention provides an optical communication system between a main office and a user/subscriber, including: at least one source/transmitter for producing a plurality of optical radiation output signals, the output signals having predetermined wavelengths and being fed to output waveguides, the source/transmitter being capable of maintaining constant intra-wavelength spacings between the output signals; a plurality of modulators, each coupled to one of at least several of the output waveguides and leading to a multiplexer; two receiver/demultiplexer units, each followed by a detector unit, and at least one pump line for passing optical radiation from the source/transmitter to the receiver/demultiplexer units. |
